public interface ResolvingToMultiple<Multiple>

This is the most generic interface for positions in the graph traversal from which one can resolve a many entities using some filters. Note that a position might not allow for ResolvingToSingle if the same type of the entity the position represents can be resolved in multiple ways - for an example, see how Environments.BrowserBase.allResources() is defined.

Method Summary

Modifier and Type	Method and Description
default Multiple	getAll(Filter... filters) Returns access interface to all entities conforming to provided filters in the current position in the inventory traversal.
Multiple	getAll(Filter[][] filters) Returns access interface to all entities conforming to the provided filters in the current position in the inventory traversal.

Method Detail

getAll

default Multiple getAll(Filter... filters)

Returns access interface to all entities conforming to provided filters in the current position in the inventory traversal.

Each of the filters is applied on the source entities. If you want the filters to be applied sequentially on the intermediate results, use getAll(Filter[][]).

Parameters:

filters - the (possibly empty) list of filters to apply.

Returns:

the (read-only) access interface to the found entities

getAll

Multiple getAll(Filter[][] filters)

Returns access interface to all entities conforming to the provided filters in the current position in the inventory traversal.

The filters parameter is actually composed of individual sets of filters each of which is applied to the "source" entities. Each set can have multiple filters that are then applied one after another on their intermediate results. This becomes useful when you want to filter by sources having some kind of relationships with other entities and in addition filter on the sources themselves, too. E.g.:

 inventory.tenants().getAll(new Filter[][]{{Related.by("myRel"), With.type(ResourceType.class)},
 {With.id("asf")}}).entities();
 

The filter above would first check that the tenants in question have a relationship called "myRel" with some resource types and then would also check if the tenant has ID "asf".

Parameters:

filters - the sets of filters to apply

Returns:

the access to found entities
